UNITED STATES PATENT OFFICEO EPHRAIM SOPER, OF BROOKLYN, E. D., NEW YORK.

THILL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 231,457, dated August 24, 1880.

Application tiled May 5, 1880.

To cli whom it may concern Be it known that I, EPHRAIM SUPER, of Brooklyn, E. D., in the county of Kings and State of New York, have invented certain Improvements in Shaft-Oouplin gs for Carriages, 85e., of which the following is a specification.

This invention is designed to provide a carriage-clip which shall be perfectly noiseless and not liable to get out of order through any wear or displacement ot' its parts; and to this end the invention comprises certain novel combinations of parts whereby the bolt of the clip is prevented from getting loose in the lugs of the clip wherein said bolt is placed; also whereby the shaft-iron is prevented from moving laterally upon the bolt or coming in contact with the lugs ofthe clip; also whereby provision is made for preventing the wear of the packing interposed between the shaft-iron and the clip.

Figure l is a plan view o f a shaft-coupling embracing my said invention. Fig. 2 is a vertical longitudinal sectional view of the same.

YFig. 8 is a vertical transverse sectional view thereof, taken in the line of the bolt by which the shaft-iron is connected with the clip. Fig. 4 is a detached perspective view of the said bolt and its accompanying nut; and Fig. 5 is an end view of the cylindric packing interposed between the bolt and the shaft-iron.

A is the shaft-iron, composed of two parts, c b, pivoted together, as shown at c, each of its parts having a transverse semi-cylindric recess, which, when the two parts a, b are brought together, are closed to constitute the socket e. When the two parts are thus closed and the shaft-iron is applied in place upon the clip, as hereinafter explained, the said two parts are secured together by a bolt, d, and nut f, and pass through suitable slots or openings in the said parts. Projecting inward from each ofthe opposite portions of the socket c of the shaft-iron A, about equidistant from the opposite ends of the said socket, is an inwardly-projecting rib or spline, n, which is `triangular in' its cross-section, as shown more clearly in Fig. 3.

B is the clip, having the usual shank m and tne lugs r'. rlhe distance between thelugsris greater than the width of the adjacent portion c of the shaft-iron A. In other words, the

(No model.)

said shaft-iron at the part just indicated is narrower than the space between the lugs fr, the purpose of which will hereinafter appear.

O is the bolt, of cylindric form except at the headed end, which is pyramidal in shape, as`

shown at c', in addition to the usual squarehead portion d', its opposite end being provided with the usual screw-thread, upon which is screwed a nut, g, which, in addition to the usual square portion c', has a conical part, f.

One of the lugs r of the clip B has a socket, a, of a shape corresponding to the pyramidal parts c of the head of the bolt, and in like manner the opposite one of the lugs r has a conical bearing, b, conforming to the shape of the conical partf of the nut g. When the nut is passed through the aforesaid bearing of the lug r, the pyramidal part c of the head being fitted into the correspondingly shaped socket c", and the nut g being turned and titted into the correspondingly-shaped conical socket b, it follows that the head and the nut will be drawn into their corresponding sockets very snugly and closely, and that any wear which may occur in the bearing may be quickly compensated for by simply tightening the nut, this being by the pyramidal formv of the part c' of the head of the bolt, which prevents the bolt from torsion, even when considerable t'orce is exerted upon the holt in drawing home the head and the nut to their respective bearings, as just herein explained.

E is a leather packing, formed preferably of sole-leather, of .cylindric form, designed to be placed upon the bolt O, as represented in Fig. 3, when the said'bolt is placed in position in the clip, as hereinbefore explained. In order that this packing E may hold snugly and tightly upon the bolt and be prevented from rapidly wearing out thereon, it is lined with two oppositely-placed semi-cylindric metallic plates, r', which are held in position by small tongues c, formed at their outer ends, and turned over and clinched into the adj aeent surface or substance of the packing itself, as represented in Figs. 3 and 5.

When the bolt C is forced into and through the bore s of the packing E, as represented in Fig. 3, the leather of which the packing E is composed is stretched or strained, and thereby compresses the plates r against the surface of IOO ofthe shattiron upon the bolt, and in eme ot' the wearing away of the surface ot' the said groove the loss may be compensated by more Closely tightening together the two parts n l of the shaft-iron A. Inasinuch as the lateral movement ofthe shat't-iron upon the packing E is prevented, as just explained, and inasmuch as the adjacent end ot' the shaft-iron is narrower than the space between the lugs, it

follows that the said shat't-iron cannot strike laterally against the lugs. and any noise i'roni such cause is, ot` course. thereby prevented.

What I claim as in v invention is 1. The bolt having a pyralnidal head at one f end and furnished with a conical nut at the other,in combination with the clip having one of its ears constructed with a pyrainidal socket and the other with a conical socket, whereby the bolt is snugly and securely connected and supported at its ends, with a straight parallel central portion adapted to receive the sl1at`t iron, substantially as and for the purpose herein set forth.

L. The cylind ric leatherpaeki n g constructed with a central triangular circumferential groove, in combination with the clip, the bolt, and the hinged shaft-iron constructed with the internal triangular spline adapted to tit into the groove ofthe leather packing, substantially as and i'or the purpose herein set forth.

3. The cylindric leather packing provided internally with the two opposite semicircular bearing-plates attaehed at their extremities to the said packing b v the outwardly-turned spurs, in combination with the clip, the bolt, and the shaft-iron, all substantially as and for the purpose he. ein sety forth.

4. 'lhe combination of the clip, the shaftiron having a socket narrower than thc space between the lugs ot' the clip and constructed with the internal triangular spline, the transverse bolt, and a packing or bearing construt-ted with a triangular circumferential groove to receive the spline ot' the shaft-iron, whereby the. shat'tiron is held against lateral movement without contact with the cars or l Iugsot' the clip, all substantially as and for the l purpose herein set forth.

EIHRAIM SUPER.
